Is It Safe to Take Vitamin B6 for Six Months Without Risking Toxicity?
Hello, I am a 28-year-old male, standing 1.8 meters tall and weighing 78 kilograms. I received a diagnosis of Paranoid Schizophrenia at 25 years old, after having been misdiagnosed initially. Currently, I'm prescribed 100 mg of Xeplion (Paliperidone), which has affected my libido; I was on a higher dose of 150 mg before. I have started taking 250 mg of Vitamin B6, which seems to have restored my sexual drive to its normal state. However, I am concerned about the potential risk of experiencing toxicity, specifically peripheral neuropathy. My healthcare provider mentioned that we could look at reducing my antipsychotic medication after six months, potentially lowering the dose from 100 mg to 75 mg during my last consultation. In addition to Xeplion, I am also taking 500 mg of Depakote, 500 mg of NAC, probiotics, 50 mg of Sertraline, 225 mg of Lyrica, and 3 mg of Caripiprazine. I would appreciate your insights on this matter. Thank you!

It's great that you're seeking information about your health and the use of Vitamin B6 alongside your other medications. While Vitamin B6 can be beneficial, it's important to remain mindful of potential risks including toxicity.
Main Points:
- Long-term use of Vitamin B6 can lead to toxicity, but your current dose of 250 mg is above the standard recommended daily intake.
- Peripheral neuropathy is a known side effect of excessive Vitamin B6 intake.
- Given your medication regimen and mental health status, a cautious approach is wise.
Explanation:
Vitamin B6, also known as pyridoxine, is vital for many bodily functions, including metabolism and neurotransmitter synthesis. However, when taken in excessive amounts, it can cause negative effects. The tolerable upper intake level (UL) for adults is 100 mg per day, meaning that doses above this level might increase the risk of side effects like peripheral neuropathy, which is characterized by tingling, numbness, or pain in the extremities.
Given that you are currently taking 250 mg daily for six months, you are exceeding the recommended level, which raises a valid concern. It’s important to balance potential benefits against risks, especially with your ongoing medications.
Next Steps:
-
Reduce Vitamin B6 Intake: Consider discussing with your healthcare provider the possibility of lowering your Vitamin B6 dosage closer to the recommended intake (typically around 1.3 to 2.0 mg per day for adult males).
-
Monitor Symptoms: Keep track of any new symptoms such as tingling or numbness, and report these to your healthcare provider as they may indicate early signs of neuropathy.
-
Review Medication Regularly: As you mentioned the possibility of decreasing your antipsychotic medication, maintain open communication with your healthcare provider about any changes to your treatment plan and discuss how they may affect your overall mental health and any symptoms you’re experiencing.
-
Nutritional Sources: Consider obtaining Vitamin B6 from dietary sources, such as poultry, fish, potatoes, chickpeas, bananas, and fortified cereals instead of relying heavily on supplements.
-
Stay Informed: Educate yourself about the potential interactions between Vitamin B6 and your current medications, particularly the potential effects on your nervous system.
It's wonderful that you've found some relief in your sexual drive, but safety is paramount. Please take these steps to ensure you're managing your health effectively and consult closely with your healthcare provider about any and all supplements you're considering.

Battling Chronic Nausea and Vomiting for Over Two Years
For the past two years, I (age 26, female) have been enduring an incredibly challenging health situation. I experience intense nausea daily and find myself vomiting numerous times, with almost nothing providing relief. To provide some background, I’m from West Texas and I currently weigh around 190 pounds, standing at 5’7”. Initially, my weight was about 211 pounds when these symptoms began, and it fluctuates frequently between 190 and 225 pounds. I engage in vaping and consume THC. Previously diagnosed with hypothyroidism, my condition seemingly resolved, according to my healthcare providers. Additionally, I have polycystic ovarian syndrome (PCOS). I have consistently faced irregular bowel movements, with stools that are loose and sometimes appear to have mucus. Compounding my struggles, I've also suffered from migraines. I have had an IUD for over five years, experiencing two insertions of the Kyleena device. In December 2022, my battle with health took a severe turn when I was diagnosed with stage 4 Hodgkin’s Lymphoma, requiring chemotherapy treatment, specifically AVBD (Apologies for not recalling the exact medication names). By July 2023, I had fortunately achieved remission. However, after reaching remission, my vomiting worsened, transforming from primarily white foam to a mixture of 80% bile, any food I attempt to consume, and still white foam. This intense vomiting, accompanied by significant pain in my upper back, escalated to more than eight episodes daily by November 2023. At that time, THC seemed to be the only avenue for me to retain any food. During this tumultuous period, I consulted various doctors who, after confirming I wasn’t pregnant, attributed my symptoms to Cannabinoid Hyperemesis Syndrome (CHS). Immediately, I ceased THC consumption for over six months, yet the vomiting continued unabated. Each time, doctors would prescribe ondansetron, regardless of my claims that it provided no relief. I experimented with various diets recommended by medical professionals, but there were no improvements in my condition. Eventually, I obtained a referral to a gastroenterologist who intended to perform an endoscopy. However, the procedure was prohibitively expensive even with insurance, and thus was never conducted. This doctor also ordered blood tests to rule out several gastrointestinal disorders, such as Crohn's disease, Irritable Bowel Syndrome (IBS), and gluten sensitivity, but all results came back normal. Afterward, I had another appointment with a different gastroenterologist, but the doctor failed to meet with me. Instead, a nurse informed me that the doctor had merely recommended promethazine without conducting any tests or scheduling further visits. When I mentioned the possibility of gallbladder issues, the doctor laughed dismissively at my suggestion. Discussing my situation with my oncologist, he suggested that my heightened sensitivity to food odors stemmed from my chemotherapy experiences while I was working in fast food. While food smells indeed affect me, I'm primarily triggered by medical scents such as rubbing alcohol and cleaning agents. This ongoing ordeal has been overwhelmingly distressing. I now experience episodes of vomiting accompanied by bright red blood, presumably due to a throat tear. When I first encountered this troubling symptom, I consulted a doctor who appeared unfazed and prescribed a promethazine suppository, which does help but makes me extremely drowsy. My nausea persists nearly around the clock, often feeling as if there’s a heaviness in the upper part of my abdomen. I frequent urgent care facilities when my symptoms intensify, only to be met with minimal assistance since this is a chronic issue. Currently, I lack a primary care physician. Whenever I sought one, I encountered skepticism regarding my condition, with some healthcare professionals implying that I was exaggerating my symptoms. Though many physicians who do take my situation seriously seem baffled, I've lost count of the diverse medical experts I've consulted about these ongoing issues. If anyone has insight or suggestions, I would genuinely appreciate it. I can share my latest bloodwork results if that would be helpful—just let me know!
Strange Stomach Sensation Leading to Waking Up
Greetings. I'm a 36-year-old male, standing at 172 centimeters and weighing 90 kilograms. I don't take any medications, nor do I smoke. I've been living with diastasis recti for several years now, and I may also have irritable bowel syndrome (IBS). Additionally, I deal with fatty liver and kidney stones, though I assume these last two conditions are not related to my current concern. Occasionally, I experience a peculiar sensation that jolts me awake; it feels like a quick pulsing in my stomach. I’ve noticed it tends to affect the left side when I’m lying on my left side and the right side when on my right. Remarkably, it can occur even when I’m on my back. This strange feeling often escalates into a surge that fully rouses me. Alongside this, I sometimes feel prickling sensations throughout my body and fleeting lightheadedness. When this sensation disturbs my sleep while I’m turned to my side, shifting onto my back or the opposite side might alleviate it, but not always. In instances where I awaken while lying on my back, I discovered that gently pressing my hands on either side of my stomach can help, as can rising to a sitting or standing position. However, during my last two episodes—one a couple of weeks ago and another tonight—those techniques weren’t effective right away, which made me feel a bit anxious, prompting me to seek advice. Does anyone have insight into what might be going on? By the way, I’ve undergone routine ultrasound examinations of my abdomen by two different physicians during check-ups, both of whom assured me that everything appears normal, including my abdominal aorta and internal organs. They didn’t identify any issues at that time.
Understanding Tuberculosis Exposure Risk
A 26-year-old male, who neither drinks alcohol nor smokes, seeks to understand the implications of exposure to tuberculosis (TB). As an anesthesia technician, I became concerned after I encountered a TB-positive patient about a month ago. I had to enter the patient’s room several times to perform blood gas tests. On my first entry, I mistakenly wore my N95 mask incorrectly due to the hectic nature of attending to multiple rooms. From my research, it appears that TB is quite transmissible; direct exposure can pose a serious risk of infection. Transmission usually requires prolonged contact with an infected individual, particularly in a close or face-to-face setting. In this case, the patient was lying face down and appeared to be sleeping when I entered. I have already undergone testing for TB, but I am eager to deepen my understanding of the risks involved in these situations.
24M | Unexplained Fainting Incident
**Note:** I previously shared this story, but it was inexplicably removed. I’m a 24-year-old male without any medical diagnosis or prescription medications. While I do consume alcohol occasionally, I hadn’t been drinking before this happened. Around 3 a.m., I got up from bed to use the restroom. As soon as I began to urinate, I suddenly felt a wave of dizziness. The next moment I was aware of was regaining consciousness in the bathtub, startled awake by the sensation of something dripping on me—only to discover it was my own blood. This was my first experience with fainting. When I came to, confusion set in. I was disoriented and couldn’t comprehend why I was being dripped on while in what I thought was my “bed.” Strangely, I also imagined that I was lying on a collection of marbles (which I actually don’t own)—this turned out to be the shattered glass of my shower door lying around me. I’m uncertain whether I lost consciousness first and then fell, or if the fall caused my brief blackout. It took me a few moments to understand why I was in the bathroom at all. I’m not sure how long I was out; I only remember it was around 3 in the morning when I initially got up, and about the same time when I regained consciousness. I dialed 911, and the ambulance arrived promptly. They checked my vitals, performed an EKG and measured my blood sugar, finding nothing unusual. At the emergency room, they repeated the vital checks, conducted a CT scan, drew blood, and took x-rays—yet still no abnormalities were detected. I had several cuts on my face and left arm (curiously, this is the arm that would have been turned away from the door), along with bruising around my ribs. Since the incident, I’ve been suffering from headaches and pain in my ribs. I received stitches on both my face and arm. The nurse suggested I could have stronger pain relief, but I opted for just Toradol. They eventually discharged me, stating, "We’re unsure what caused this, but return if it happens again." What might have triggered such an incident? How can I safeguard against it reoccurring if they remain uncertain about the cause?
Swelling Beneath My Chin Near the Jawline
18-Year-Old Male: I'm reaching out to any medical professionals who might provide insights into my situation. I've been using marijuana since I was 14, but now, at 17, I'm making an effort to stop and have been clean for 18 days. Recently, I've discovered an unusual swelling located just beneath my chin, behind my jaw. It causes some discomfort when I move, yet it doesn’t feel painful continuously. I'm somewhat anxious that this could be indicative of a more serious issue, especially considering it's positioned near my chin's lymph nodes. Any advice or information would be greatly appreciated as it might help alleviate my worry.
